This guide listed 234 rooms at the Disneyland Hotel.
From 1959 Travel Brochure
This is the only reference I have ever found mentioning 234 rooms. All other guidebooks and brochures always list "over 200 rooms" in them with no exact number. This was the short-lived 1959 layout of the Disneyland Hotel. In 1960, two new Garden Structures were added pushing the total to over 300 rooms. I have yet to see a reference to the exact number in 1960 but I have hope that I will find this information. Previously, I never had a printed source for the 234 rooms either.
